Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] 1. As attached figure 1 As shown, the present invention is a device designed for the air intake and exhaust emission of marine robots when the diesel engine is powered, and is composed of an air intake part and an exhaust part. Air controller, intake and exhaust controller drive hydraulic valves, electric ball valves, and drainage pumps according to control commands, and at the same time, the intake and exhaust controllers feed back the working status to the upper control computer through the CAN bus to realize automatic control. figure 1 The middle pipeline system is connected to the intake and exhaust controller, and the "open circuit" in the figure does not mean that it is not connected, but means that the connection between the pipeline system and the intake and exhaust controller does not affect the internal connection relationship...

Abstract

The invention relates to the field of an ocean robot and specifically relates to an air intake and exhaust device and method for the ocean robot; an upper control computer is connected with an air intake and exhaust controller by means of a CAN (Controller Area Network) bus and is adopted to receive real-time signals fed back by the air intake and exhaust controller and send a control command to the air intake and exhaust controller; the air intake and exhaust controller is connected with an air intake and exhaust pipeline system by means of an I / O interface and performs real-time communication with the air intake and exhaust pipeline system, so that the automatic control of the air intake and exhaust controller working in an enclosed environment on the sea is realized; compared with an air intake and exhaust system of a land diesel engine, the air intake and exhaust device is relatively rational in design of temperature drop, noise reduction and waterproof performance.

Description

technical field [0001] The invention relates to the field of marine robots, in particular to an intake and exhaust device and method for marine robots. Background technique [0002] Compared with the above-mentioned air intake and exhaust devices for land-use diesel engines, there are special requirements for the intake and exhaust units designed for the air intake and exhaust emission of marine robots when the diesel engine is powered: [0003] (1) Exhaust back pressure problem. The allowable exhaust back pressure of the diesel engine is small, if the exhaust back pressure exceeds the allowable value of the main engine, it will affect its power performance. [0004] (2) Exhaust gas cooling problem. When the diesel engine is in use, the exhaust gas will generate a certain amount of heat. Due to the limited internal space of the marine robot, the exhaust gas must be cooled without increasing the volume. [0005] (3) Prevent the influx of seawater, causing the diesel engine...
